Tetrabutylammonium hydroxide Chemical Properties,Usage,Production

Chemical Properties

Aqueous solution.

Uses

Tetrabutylammonium hydroxide(TBAOH) is a quaternary ammonium salt mainly used as a strong base and phase-transfer catalyst. TBAOH may be used as an ion-pairing reagent in mobile phase preparation for reverse phase ion-pair high performance liquid chromatography during chromium (III) and chromium (VI) determination.

Preparation

Tetrabutylammonium hydroxide was prepared by the ion exchange between gel type strong basic anion exchange resin(OH-) and aqueous solution of tetrabutylammonium bromide.

General Description

The product is 54.0-56.0% solution of tetrabutylammonium hydroxide in H2O. Tetrabutylammonium hydroxide has been synthesized from tetrabutylammonium iodide. TBAOH dissolved in anhydrous isopropyl alcohol is widely employed as titrant for weak acids.

Flammability and Explosibility

Flammable
